A task in which it is necessary to create regular expressions to define five different languages. The alphabet used is A = {a, b}. The languages ​​are:

L1, which has exactly one "a" but any number of "bs".

L2, which has an odd number of "as" and an even number of "bs".

L3, which contains exactly two "as" or exactly two "bs", although not necessarily adjacent.

L4, which has all "bs" appearing before any "a" or all "as" appearing before any "b".

L5, where there can be any number of "as", but the number of "bs" must be even, although the "bs" need not be adjacent.

Answer:

(C) -6

Step-by-step explanation:

Given the following data;

Points on the graph (x1, y1) = (1, -9).

Mathematically, the equation of a straight line is given by the formula;

y = mx + c

Where;

m is the slope.

x and y are the points

c is the intercept.

To find the zero of the linear function f, we would use the following formula;

y - y1 = m(x - x1)

Substituting into the formula, we have;

y - (-9) = -3(x - 1)

y + 9 = -3x + 3

y = -3x + 3 - 9

y = -3x -6 = mx + c

Intercept (c) or zero of a function = -6

ASA

Step-by-step explanation:

We know that <YPC and angle <YPX are congruent angles.  They are both 90°.

Side YP is congruent to YP, so these sides are congruent in both triangles.

<XYP and <YPZ are congruent, because the perpendicular bisector cuts <XYZ in two equal parts.

Answer:

30.5

Step-by-step explanation:

Answer: A y-intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system.

Slope - A number that describes both direction and steepness of the line.

Step-by-step explanation: If a line intersects the y-axis at point 5 then its y-intercept will be c= 5. As we denote y-intercept with c.

The slope is denoted by m.

To simplify this expression, you can first simplify the logarithms by using the properties of logarithms and the simplified expression is -0.00195

A logarithm is a mathematical function that is used to determine the power to which a number must be raised in order to produce a certain value. The logarithm of a number "b" to base "a" is represented as loga(b) or logb. The logarithm of b to base a is equal to the exponent to which we must raise a to get b.

[tex]1/2 Log10 25/4 - 2 log10 4/5 + log10 320/125[/tex]

To simplify this expression, you can first simplify the logarithms by using the properties of logarithms.

= 0.397940008672037 - 1.204120018655925 - 1.397940008672037 + 0.40825006983185

= -0.2 - 0.2062 + 0.40825

= -0.00195

Complete question is: simplify the given equation:  1/2 Log10 25/4 - 2 log10 4/5 + log10 320/125

Mr.West ate 23 ounces of grapes in 11 days by eating 2 1/11 ounces of grapes each day.

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, Mr.West ate grapes for 11 days. He ate 2 1/11 ounces of grapes each day.

Therefore, The total number of grapes Mr.West ate is,

= 11×(2 1/11) grapes.

= 11×(23/11) grapes.

= 23 grapes.
So, He ate 23 ounces of grapes in 11 days.

Step-by-step explanation:

Answer:

The tourists will meet at the midpoint of the bridge, which is 2738/2 = 1369 meters from each end.

At their respective walking speeds, it will take the first tourist 1369/0.9 = 1521.67 seconds to reach the midpoint, and it will take the second tourist 1369/1.1 = 1242.73 seconds.

Therefore, it will take them a total of 1521.67 + 1242.73 = 2764.4 seconds to meet.

Since there are 60 seconds in a minute, the time in minutes is 2764.4 / 60 = 46.07 minutes.

Therefore, it will take the tourists 46 minutes and 0.4 seconds to meet.

On solving the provided question we cans ay that - here in linear equation, y = 3 and x = -1/2

The algebraic equation y=mx+b is known as a linear equation. B is the y-intercept, and m is the slope. The previous sentence, where y and x are variables, is commonly referred to as a "linear equation in two variables." Bivariate linear equations are those that contain two variables in them. The linear equations 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3 are examples. When an equation has the formula y=mx+b, with m denoting the slope and b the y-intercept, it is referred to as being linear.

y = 2x + 1 - linear equation.

value of y;

[tex]x = 0\\y = 2(0) + 1\\y = 2 + 1\\y = 3[/tex]

value of x;

[tex]y = 0\\0 = 2x + 1\\2x = -1\\x = -1/2[/tex]
